Thanks again James. The 6B's on my DQ-10's really sing. The single 6B on the DW-1 subs has great bass, but I am missing the subs in stereo on some newer material and may have to go back my Rotel. Anyway.... if this is your guys idea of planned obsolescence keep it up, very pleased with the sound and I'll be hanging out in the 80's for a bit longer.
